Cameron McGeehan has challenged Pompey to bounce back from their slender defeat to Coventry.
The Blues had won nine games in succession before suffering late frustration against their fellow promotion chasers at St Andrew’s.
Matty Godden came off the bench to settle a contest that was lacking in goalmouth action throughout.
But McGeehan is now targeting another run to ensure that Pompey quickly get their Championship challenge back on track.
The midfielder said: “It’s a tough one to take because we were on top in the second half and then conceded a really sloppy one.
“With the form that we’re on, I thought that a goal was coming for us, but instead the game was taken away from us at the end.
"The important thing is really how you respond to that disappointment and make sure that it is just a blip."
“I’m sure it will just be a small setback, though, and now it’s important that we’re able to kick on again.
“It was pretty stale, but I think we stepped up and began to put a bit of pressure on Coventry on a tough pitch.
“We’ve not conceded many goals recently, but every now and then you will and you’ll lose a game – it’s part of a parcel of a season.
“The important thing is really how you respond to that disappointment and make sure that it is just a blip.
“We want to put another run together from now until the end of the season, so we’ve got to keep going.
“Were good enough and I’m confident that we’ll be there or thereabouts because the wins will come for us.”
